Generate a 1000-Length Binary Random Sequence and Analyze Line Coding Schemes

A. Generate a 1000-length binary random sequence with P(0)=0.8 and P(1)=0.2; B. Apply Return-to-Zero AMI encoding (50% pulse width, 8x symbol rate sampling), plot waveforms for first 20 symbols; C. Implement HDB3 coding and plot corresponding waveforms; D. Switch to Miller coding and visualize waveforms; E. Perform power spectrum estimation for all 1000 symbols; F. Observe AMI power spectrum variations with changing source probabilities. Includes MATLAB implementation details for random sequence generation, coding algorithms, and spectral analysis.
